Compares two paths lexicographically.

1) Checks whether lhs and rhs are equal. Equivalent to !(lhs < rhs) && !(rhs < lhs).
2) Checks whether lhs and rhs are not equal. Equivalent to {{{1}}}.
3) Checks whether lhs is less than rhs. Equivalent to lhs.compare(rhs) < 0.
4) Checks whether lhs is less than or equal to rhs. Equivalent to !(rhs < lhs).
5) Checks whether lhs is greater than rhs. Equivalent to rhs < lhs.
6) Checks whether lhs is greater than or equal to rhs. Equivalent to !(lhs < rhs).

[edit] Notes

Path equality and equivalence have different semantics.

In the case of equality, as determined by , only lexical representations are compared. Therefore, path("a") == path("b") is never true.

In the case of equivalence, as determined by std::fs::equivalent(), it is checked whether two paths resolve to the same file system object. Thus equivalent("a", "b") will return true if the paths resolve to the same file.
